MOVABLE LAMP-CONE.

SPECIFICATJ ION forming part of Letters Patent No. 247,821, dated October4, 1881,

Application filed May a, 1879.

To all whom it may concern:

Be it known that I, HENRY J. HAIGHT, of the city,eounty,and Stateof NewYork, claim to be the sole and original inventor of a Machine for Regulating the Igneous Heat in Poultry-Hatching Machines, which I denominate Haights Movable Lamp-Gone, the material and construction being set forth and described, reference being bad to the drawings herewith sent, in the following specification.

Figure 1 is a perspective elevation with parts broken out, and Fig. 2 is a plan view, of my construction.

My invention consists of certain improve-- ments in the lamp-cone used in my rotary incubator, patented December 26, 1871, which are as follows:

The rod R, Fig.1, entering the lamp-vessel L by the way of a perforation made in the vessel, is twisted in the first crank, a, and proceeds up to the second crank, b, which is turned over the peg P, jutting from the lampcone 0. It continues its conrse down to the third crank, c, and horizontally to the fourth crank, 11, and up again to the fifth crank, e, which turns over thepeg P on the other side of the cone, runs down to the sixth crank, f, and finally goes out of the vessel. By the rod outside the vesthe flameextinguishing tube is raised by means of a bent rod turning on its axis and a connecting-link between the said rod and tube. My invention, besides being differentin construction from such a device, is for an entirely differentpurposenamely, for automatically regulatiug the height of a cone or tube around the burner, acting as a deflector and heat-regulator.

I claim as my invention The combination of the rod It, twisted in cranks a b c (1 cf, and the pegs of the lampcone 1? P, substantially as described.
